Book Description

The report summarizes the corrosion behavior of beryllium. The effects on beryllium of the following environments are considered: moisture, salt solutions, acids, alkalis, gases, organic liquids, molten materials, and solid materials. Stress-corrosion cracking and galvanic effects are also discussed. A final section of the report reviews various types of coatings for protection of beryllium from corrosion by a variety of environments.

Book Description

This report discusses the powder metallurgy of beryllium from the preparation of powders through the production from the powders of solid products. Various methods of powder compaction are presented including die pressing, isopressing, slip casting, vibration packing and explosive compaction. Sintering, and methods of elevated temperature consolidation, including vacuum hot pressing, hot isostatic pressing, forging, extrusion, and plasma spraying, are discussed. The final sections of the report cover properties of powder beryllium products, applications of beryllium prepared by powder metallurgy and current trends in the powder metallurgy of beryllium.

Book Description

This report supplies information on joining processes applicable to titanium and its alloys in sheet metal applications, primarily related directly to airframe construction. Although the material presented here does not cover all titanium joining processes, and omits such processes as plasma-arc, submerged-arc, electroslag, flash, and high-frequency resistance welding, the data presented cover materials up to 2-inches thick in some cases and the report should be useful to anyone seeking titanium joining information. The joining processes covered fall into five categories: welding, brazing, metallurgical bonding (diffusion and deformation bonding), adhesive bonding, and mechanical fastening. The fusion welding processes that are discussed in detail include gas tungsten arc, gas metal arc, arc spot, and electron beam. The resistance processes give extended coverage are spot, roll spot, and seam welding. (Author).
